I recently stumbled upon this discussion thread and was wondering if this solution could be useful for SM 2.46 under Win-XP Pro, though the Adobe plugin mentioned is not included with the SM 2.46 installation:

Are you suggesting that you have already tried to install the Adobe Primetime Content Decryption Module in Seamonkey browser and subsequently could not get H.264 video playback to work? That plug-in seems to be included with Firefox. I'd like to know if it's possible to download it somewhere.

Not sure that procedure would result in the correct installation of a plug in, as many plug-ins no longer use the PLUGINS folder within the Seamonkey program folder. For example, Flash player installs elsewhere and not in the SM browser's plugins folder any longer, even under Win-XP. It would be necessary to have the original plug-in installer to do the job right, which is why I'd like to have the plugin installer.

Interesting. I stumbled on this to find a solution in Mageia 6 Linux. Same thing. No plugins folder. I want to use either H.264 or x264 as a plugin. Any ideas on how to get one of them recognized by Seamonkey?

Thanks.

This was about SeaMonkey on WinXP and not Linux. Microsoft does not provide the codecs needed for HTML5 player for WinXP as they do for Windows Vista and later which is why the OP was looking for work arounds.

If you are not able to fully use the HTML5 player at youtube then your problem could be due to not having needed FFmpeg packages installed as Gstreamer has not been used for quite some time now.
